摘　　要：介绍了整体桥台桥梁的特点、存在的问题和有限元分析方法,并对一座单跨整体桥梁进行了三维有限元分析,给出了在桥梁整体升温和桥面板局部升温两种荷载模式下整体桥台桥梁的荷载效应。This paper introduced the characteristics, existing problems and finite element analysis method of integral abutment bridge. A 3 D finite element analysis was performed on a single span integral abutment bridge, and the load effects under whole temperature rising of the bridge and local temperature rising of deck were compared.

关 键 词：整体桥台 桥梁 有限元分析
